Abstract

The interfacial ordering of the alkylcyanobiphenyl family of liquid crystal molecules is studied on the MoS₂ and graphite surfaces and found in both cases to arise from registry with the substrate. Aromatic and aliphatic groups are observed to have different contrasts in tunneling microscope images, with the aromatic/aliphatic contrast difference being much higher on graphite than on MoS₂.
